# Showcase

The full XWUIBarcodeCode93 range on one screen: the supported character set (digits, uppercase letters and the `- . space $ / + %` punctuation), bar geometry (module width, height, quiet zone), every knob on the human-readable line, and how density holds up as the payload grows.

It closes with a printable asset tag and a live re-encode driven by `setData()`. The two CODE93 check characters are computed and encoded for you, so the printed text stays exactly what you passed. Bars stay black on white because scanner contrast is a hard requirement, so the canvas ink is deliberately not themed.
